Is it a cause of concern if I dont have any route marked as default ?
I see so when i use the netstat command

Yes. You need a default router specified because that is the
address that becomes your gateway to the rest of the network.

You also need a nameserver specified in your /etc/resolv.conf file
unless you plan to manually specify every other host you wish to talk to.

with the above assigned IP address and net-mask I'm reading to make it

ifconfig em0 up also doesnt help ping my LAN.

the ifconfig -a output now reads the IP I just added, as well as the
net-mask & the 100 Mbps active linnk.

quick question :

I did an ifconfig em0 1.1.1.2 yday.should this be done everytime I
restart
my application, is it some kind of a temporary address assignment,
bcos
whatever I assigned was not visible today when I re-booted and I had
to do
it again, probably I should set this in the conf file also ? maybe as
another user said my NIC is not enabled or something like that.

You have to put it in /etc/rc.conf so it will be taken care of during
network initialization each time you boot. Everything at startup
reads the /etc/rc.conf and finds variables it needs to do its startup
and network startup does that too. So, you put in a line like:

ifconfig_em0="inet 1.1.1.2 netmask 255.255.255.0"
and
defaultrouter="1.1.1.3"

Amongst a number of other startup settings in /etc/rc.conf

network startup sees those and says 'oh, I know what to do with those'
and runs the ifconfig, etc.
Note that putting it in rc.cong only causes a 'ifconfig_em0' variable
to be set to "inet 1.1.1.2 netmask 255.255.255.0"
and the 'defaultrouter' variable to be set to "1.1.1.3"
It is up to the startup programs to do something about it.

The startup programs are generally run from the /etc/rc script and
from other scripts that it runs.

In the 'ifconfig -a' output you posted earlier, the 'em0' (your
desired
interface) interface neither has any IP address assigned to it, nor
its UP
.
So, if you've assigned an IP address to 'em0', then also make sure
its UP,
by
doing 'ifconfig em0 up' .
